We present a theoretical and numerical investigation of effect of a weak coherent holding radiation on transverse field structures in a wide-aperture laser with fast saturable absorption. In the absence of the coherent driving, the laser is able to support various types of “free” bright solitons. We show that even weak driving can control their topology making the scheme promising for topologically protected information processing.
